I'd only want to know if you are keeping your pelvis too upright on the saddle and then bending your lower back more to get your riding position on the bike. If so, that might contribute to your lower back hurting toward the rides end.
Rotating your pelvis forward to straighten your back might run into issues with that saddle nose up. Lowering that nose on the saddle might need you to shorten the stem or get bars with a shorter reach in them or moving the saddle a cm or so forward in the seat post. Or pedaling with more power output for the entire ride..... don't we all wish we could do that!
But there is that being on a trainer thing. I don't do trainers, so I've no idea how that translates to real road cycling. I'd be sure some things don't work the same for fit.
I went on a 100 km ride today with the nose of my saddle close to level. No lower back pain or neck pain, felt really comfortable but I kept shifting towards the front of the saddle when doing efforts. On my next long ride, I'll test out a flat one from my friend. I find that the flared rear puts a lot of pressure on my sit bones. Hopefully a flatter profile alleviates that.
